The Atlanta Journal-Constitution reported Wednesday that Jackson planned to play Sunday against the Arizona Cardinals. On Thursday, the veteran running back clarified that when he said he was ready to "give it a go," he was referring to practice, not a game.

Jackson has been out since Week 2 with a strained hamstring. He did make his practice debut Wednesday, a positive sign he could be close to a return to game action.

3. Minnesota Vikings running back Adrian Peterson revealed Thursday that a bruised hamstring has made him "hesitant" in recent weeks. The reigning MVP said he's been dealing with the issue for "four to five weeks," but he believes he's now cleared the mental hurdle that's come with the injury. Fun fact: Peterson must average 149 rushing yards per game for the rest of the season to hit the 2,000-yard milestone again.

6. Cowboys running back DeMarco Murray practiced for the second consecutive day. He's on track to play Sunday after missing last week with a sprained knee.

7. Cowboys wide receiver Miles Austin continues to be held hostage by his balky hamstrings. Austin was held out of practice Thursday, a day after working with teammates on a limited basis. With Terrance Williams playing well in the No. 2 receiver role, don't be surprised if Austin sits until he gets closer to 100 percent.
